In that context, oscillating RGs in SB2 EBs are perfect targets to verify the accuracy of masses and radii obtained with asteroseismology.
[1]} find that the strict application of the scaling laws as defined by [2]} leads to overestimating masses and radii by about 25% and 10%, respectively.
Corrections of the asteroseismic scaling relations that were proposed at the time [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]} reduced these discrepancies to 15% and 5%.
Since then, new corrections to the seismic scaling relations have been proposed [10]}, [11]}, [12]}.
[13]} find excellent agreement between radii obtained through the asteroseismic scaling relations and those computed from TGAS parallaxes [14]}.
[15]} obtain additional radial velocities for three sources that were previously observed by [1]} and show that the correction published by [10]} improved the accuracy of the seismic estimates of mass and radius.
[18]} report the detection of an 11th pulsating red giant in an eclipsing binary and propose new “solar” reference values by showing that it leads to a better agreement. Theoretical studies based on RG in EBs have already been undertaken to constrain stellar models. For example [19]} obtain a better agreement between the dynamical and asteroseismic masses by increasing the convective overshoot by about 14 %. Besides, [20]} suggest that differences between the composition profile of the stellar models and the actual profile could explain part of the current mismatch between the dynamical and seismic masses and radii. More such benchmark systems are needed to go further.
